The invention discloses a battery current limiting protection method, device and equipment and a storage medium, and the method comprises the steps: determining a first execution target torque of each bridge motor according to the peak power of each bridge motor and the peak power of a power battery; determining a torque dynamic change value of each bridge motor according to the peak power of the power battery, the discharge power of the power battery and the first execution target torque; and according to the first execution target torque and the torque dynamic change value, the final target torque of each bridge motor is determined. The power of the power battery is distributed in real time based on the peak power of each axle motor, cooperative change of the multiple axle motors and protection of the power battery of the vehicle are achieved by distributing the torque dynamic change value in real time, the over-discharge problem of the power battery in the rapid acceleration and rapid deceleration driving process is avoided, synchronous change of the axle motors is achieved, and the service life of the vehicle is prolonged. And automobile driving abnormity caused by asynchronous torques between the axle motors is avoided, and the automobile driving reliability and safety are greatly improved.

    本发明公开了一种电池电流限制保护方法、装置、设备以及存储介质,其中方法包括:根据各桥电机峰值功率和动力电池峰值功率,确定各桥电机的第一执行目标转矩;根据动力电池峰值功率、动力电池放电功率以及第一执行目标转矩,确定各桥电机的转矩动态变化值;根据第一执行目标转矩和转矩动态变化值,确定各桥电机的最终目标转矩。本发明基于各桥电机峰值功率对动力电池实施功率进行实时分配,通过实时分配转矩动态变化值实现多个桥电机协同变化并对车辆动力电池保护,既避免急加速和急减速行驶过程中动力电池出现过放问题,又实现各桥电机的同步变化,避免桥电机之间的转矩不同步导致汽车驱动异常,极大地提高了车辆行驶可靠性和安全性。
